Caves & Cliffs

Official logo for Caves & Cliffs.

Caves & Cliffs is the name for an upcoming major update that will be released in 2021 for most versions of Minecraft, likely as Java Edition 1.17 and Bedrock Edition 1.17.0. It was announced in Minecraft Live 2020. It will include new cave and mountains features, as well as the glow squid, a mob that was voted for during the second Minecraft mob vote.

Lightning Rod

"Lightning Rod" redirects here. For the item in Minecraft Dungeons, see MCD:Lightning Rod.

• Crafted with copper.
• Redirects nearby lightning strikes to the top of the rod, which can prevent flammable structures from catching on fire during thunderstorms.

Powder snow

• Similar to snow, but entities fall through it, similar to traps or the "snowier snow" announced when the Mountains won the 2019 biome vote.
• This is how regular snow layer blocks worked in old versions of Minecraft, but it was changed because it created accidental booby-traps when lava ponds generated at the right height to cut out the ground but not the snow.

File:Unidentified Stalagmite Torches.png File:White candles.png Candles https://twitter.com/beta_mcpe1/status/1312850769184518147

File:UnknownWhiteStoneBlock.png Moonstone

• Similar to diorite, but with a smoother texture.
• Found underground surrounding the outsides of geode formations.

White stone

• Found in lush caves

File:Unnamed Underwater Stone Block.jpeg Seastone

• Seen in a Twitter post highlighting underwater geodes.
• Might be found in any oceans, or only found near underwater geodes.
  • It has been speculated that this might instead be a side texture of the Amethyst Geode Block that shows facing away from the inside of a Geode, alluding to Geodes in real life and functionally similar to Mushroom Blocks.
  • A secondary speculation is that they may have some relation to the blocks that make up the walls in "the Warden's dungeon," which seem to have a similar texture.

Items

Amethyst Shard

• Drops from Amethyst Crystals.
• Used to make telescopes.

File:Axolotl Bucket JE1.png Bucket of Axolotl

• Obtained by using a water bucket on an axolotl, similar to fish.
• Had no name in the Minecraft Live 2020 demo, showing its translation string "item.minecraft.axolotl_bucket".

Brush

• Used to sweep away debris from archaeological items
• Sweeps debris off archaeological items one layer at a time, but similar to the block breaking animation, does not permanently change the look of the block it is used on
• Also comes in a blue variant:
• Currently using placeholder art, according to Jasper Boerstra.

File:Bundle full.png Bundle

• Can contain one cumulative stack of any variety of item types.
  • Stack sizes are sustained. For example, a bundle containing 32 blocks with a stack size of 64 could only hold an additional 8 ender pearls, as the stack size of an ender pearl is 16; the half-stack of ender pearls added to the half-stack of blocks is calculated as one full stack. Unstackable items like minecarts remain unstackable.
• Items are added by dragging bundle to an item.
• Tooltip shows icons of contained items.
• Items drop to inventory when right clicked.

Ceramic Shards

• Obtained with a brush at archeological sites.
• Come in different colors and different designs, each depicting a different picture, such as an ender dragon, Alex, a skeleton, a tree and a vindicator.

• Currently using placeholder art, according to Jasper Boerstra.

Glow Berries

• Can be eaten.
• May be able to use as a light source.

File:Telescope.png Telescope

• Crafted from amethyst shards and copper.
• When held, allows the player to see far away through a small ellipse.

Spawn Eggs

• Spawn eggs for the new mobs will likely be added.
• The Warden is the only known mob with a spawn egg visually confirmed. https://twitter.com/kingbdogz/status/1313451032383574017

Mobs

Axolotl

"Axolotl" redirects here. For the music track, see Music § Underwater music.

• Small, critically-endangered Mexican salamanders found in bodies of water within lush caves biomes.
• Will be the first ever amphibian added to Minecraft.
• Can be caught in a bucket like with fish.
  • Can be tamed by capturing it in a bucket.
• Come in different colors (leucistic, yellow, green, brown, and purple/pink).
• Plays dead when damaged, receiving Regeneration. Appears to turn invisible or teleport after this, although the latter may be just a bug or a glitch.
• Attacks drowned, guardians, elder guardians and fish.
• Sometimes can give Regeneration to the player who tamed it.

Glow squid

"Glow Squid" redirects here. For the mob in Minecraft Earth, see MCE:Glow Squid.

• Originates from Minecraft Earth.
• Glows in the same way that magma cube cores, blazes and the eyes of spiders, drowned, vexes and endermen do.
• Lives in flooded caves.

Goat

• Spawns in mountains biomes.
• Can jump very high to avoid obstacles, about 5 blocks tall.
• Attacks nearby animals by charging and knocking them a considerable distance.
• There is a baby variant, suggesting a way to breed them.

Warden

• Spawns in the new deep dark biome.
• It is the first blind mob.
• When sensing movement, it moves towards the source of the movement.
  • When attacked, it heads towards the player.
  • Seems to follow the same rules as the sculk sensor when detecting noise.
  • Does not detect players that are sneaking.
• Incredibly strong (at most 30 × 15 damage), bringing players wearing full netherite armour to 7 health points.
• Gets stronger when attacked more; stronger with less health.
• Has at least 84 × 42 health points.
• At least as fast as the player's walking speed.
  • Seems to move faster when attacked.
• Becomes aggravated when attacked, and at a certain point, will follow the player continuously regardless of any other distractions.
• Seems to have some knockback resistance.
• Likely spawns in relation to the hut seen in the clip (now called the warden’s dungeon).
• Throwing any projectile, i.e a snowball, near the Warden will cause the mob to head to the location of where the projectile was thrown, due to the projectile itself creating movement and noise, therefore distracting the warden.
• The Warden's chest has a glowing core that appears to brighten and dim in tandem with the ambient lighting of the deep dark cave biome.
• Will possibly attack other mobs.

World generation

Amethyst geode

• A tiny underground cave-like feature.
• Contains geode blocks and the amethyst crystals they generate.
• Twinkle-like sounds can be heard near amethyst crystals. It is currently unknown as to what causes the sounds.

Archaeological excavation

• A new structure where archeological items and ceramic shards can be found.

Deep dark

• New biome at the "deepest depths of the world".
• Wardens can spawn here.
• Contains candles.
• Contains sculk blocks, a new block which responds to sound.
• Contains rubble blocks.

Dripstone caves

• A massive cave biome containing vast quantities of stalactites and stalagmites.

Lush caves

• Generate below azalea trees.
• Contain glow berries.
• Can spawn axolotls.

Mesh Caves

• Seems to be possibly a large tunnel-like cave.
• Not much is known about this biome yet, but it was confirmed on Twitter by Henrik Kniberg.

General

• More extreme and smooth terrain.

Gameplay

Archaeology

• The player can find items and blocks in gravel and dirt inside the dig site structure by using the brush.
• Possible items shown in the preview footage include:
  • Ceramic shards of varying color which depict different images.
  • Diamond blocks and Emerald blocks maybe not include in the list, because that was as placeholder.

Dark flashing

• While in the deep dark cave biome, the ambient lighting occasionally dims, limiting the player's visibility. This serves a warning that the warden is nearby.

Vibrations

• An action can cause vibrations in the air, which can be picked up by sculk sensors and wardens
• Can be caused by walking, block placing, block breaking, doors or trapdoors opening, chests of any kind opening, pistons activating, and projectiles such as snowballs, eggs, or arrows landing.

Planned changes

World generation

Caves

• Revamped to generate bigger, more adventurous caves.

A picture of the local water levels in use forming an underground lake or ocean shown in Minecraft Live 2020.

Local water levels

• A new generation aspect has been introduced, which allows for certain areas of a world to generate with a water level different than another area.
• Allows for the generation of larger underground lakes and connections to oceans.
• Allows for the generation of many underground waterfalls.
• Allows for underwater entrances.

File:Caves & Cliffs Mountains largersize.png

The preview of updated mountain generation given during Minecraft Live 2020.

Mountains

• Revamped, featuring some new small spruce trees on the slopes and ice or packed ice above the peaks.
• Contain snow blocks, powdered snow and goats.

Mineral veins

• Will be revamped, possibly to balance the generation of copper.
  • When that stone is mined, more of the ore will be found behind it.

Trivia

• This is the first update to add a new ore to the overworld since Java Edition 12w21a in 2012 for Java Edition 1.3.1 when emerald was added.
• This is the first update to add a real-world metal into the game since Java Edition Classic 0.0.14a in 2009, which brought both iron and gold.
• Although the axolotl will be the first amphibian mob implemented into Minecraft, it was not the first announced one, since frogs were announced during the 2019 biome vote.
• Despite ores being shown to emit light during the reveal of this update, this was later confirmed to be just for demonstration purposes, in order to give a much more clearer vision for viewers, and not for the final version.
